Moist heat comes in many forms, including steam towels, hot baths, moist heating packs, etc. It helps to increase tissue elasticity, making it ideal for patients with dry and/or aging skin. Most experts recommend moist over dry heat. Not only is there less of a concern for skin irritation, it is also able to penetrate more deeply into the skin.
These hot packs are typically wrapped in several layers of towels in order to prevent burning. They can be applied onto the problem area for up to twenty minutes. Any redness they may cause should go away within six hours. Reusable heating pads are ideal, and will save you money in the long run.
